Speaker Test

[MazdaTree]

i dont know if this is in the manual or not but if you got a stock HU you can test your 4 speakers in each door

step 1: while CD or Radio is on Press and HOLD ON/OFF knob
step 2: while holding on/off press and hold the text knob (it says text right under it) until you hear a beep then let go and it will each one of ur speakers will come on one at a time and then to stop just shut off the HU and turn back on

If you needed to test all speakers you could just play with the fade and balance to test each one. I dont know what testing each one would do for yah though. Ok it works! :p
